Levels of three inflammation markers, C-reactive protein, serum amyloid A protein and procalcitonin, in the serum and cerebrospinal fluid of patients with meningitis.
The levels of C-reactive protein (CRP) and serum amyloid A protein (SAA) in blood are increased in patients with inflammatory diseases as acute phase proteins. Most of the presently used indicators of inflammation, such as body temperature, white cell count, erythrocyte sedimentation rate or CRP, are non-specific parameters. In contrast, procalcitonin (PCT) has been reported to be selectively induced by severe bacterial infection during the systemic inflammatory response syndrome (SIRS), and also in sepsis or multiorgan dysfunction syndrome. ⋯ Among those with bacterial meningitis, the serum PCT level was more elevated in those with more serious bacterial meningitis. The PCT level in the CSF did not significantly differ among the patients with the three types of meningitis. However, the serum PCT level was very high above 0.1 microg/L in all seven bacterial meningitis patients, especially in the clinically serious cases.
